Description

Elektromedizinische VorrichtungElectromedical device
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine elektromedizinische Vorrichtung zur Erzeugung eines elektromagnetischen Wechselfeldes mit einem Träger für wenigstens eine elektrische Erregerwicklung.The invention relates to an electromedical device for generating an electromagnetic alternating field with a carrier for at least one electrical excitation winding.
Stand der TechnikState of the art
Um bestimmte therapeutische Wirkungen zu erzielen, werden die zu behandelnden Körperteile dem Einfluß elektromagnetischer Wechselfelder ausgesetzt. Zu diesem Zweck werden üblicherweise elektrische Leiter in mattenartigen Trägern in Form von Erregerwicklungen verlegt, um die mit den Erregerwicklungen versehenen mattenartigen Träger als Unterlage oder als Auflage für den zu behandelnden Körperteil eines Patienten zu verwenden. Nachteilig bei diesen bekannten Vorrichtungen ist vor allem, daß die Erregerwicklungen kaum mit der erforderlichen Genauigkeit gegenüber den zu behandelnden Körperteilen ausgerichtet werden können. Die Wicklungsanordnung ist ja innerhalb der Trägermatte vorgegeben, was eine vorgegebene Verteilung des elektromagnetischen Feldes mit sich bringt. Außerdem ist eine lagegenaue Anordnung der Trägermatten gegenüber den zu behandelnden Körperteilen schwierig.In order to achieve certain therapeutic effects, the parts of the body to be treated are exposed to the influence of alternating electromagnetic fields. For this purpose, electrical conductors are usually laid in mat-like carriers in the form of excitation windings in order to use the mat-like carriers provided with the excitation windings as a base or as a support for the body part of a patient to be treated. A disadvantage of these known devices is above all that the excitation windings can hardly be aligned with the required accuracy with respect to the parts of the body to be treated. The winding arrangement is predefined within the carrier mat, which entails a predefined distribution of the electromagnetic field. In addition, it is difficult to position the carrier mats precisely in relation to the body parts to be treated.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt somit die Aufgabe zugrunde, eine elektromedizinische Vorrichtung zur Erzeugung eines elektromagnetischen Wechselfeldes der eingangs geschilderten Art so auszugestalten, daß bei einer einfachen Hand- habung eine genaue Ausrichtung der elektromagnetischen Wechselfelder gegenüber den zu behandelnden Körperteilen ermöglicht wird.The invention is therefore based on the object of designing an electromedical device for generating an electromagnetic alternating field of the type described at the outset in such a way that with a simple manual have a precise alignment of the alternating electromagnetic fields to the body parts to be treated is made possible.
Die Erfindung löst die gestellte Aufgabe dadurch, daß die Erregerwicklung einen vom Träger gesonderten, von einer Hülle umschlossenen Spulenkörper bildet, daß der Träger aus einem um einen Körperteil schließbaren Band besteht und daß der Spulenkörper über die Hülle auf dem Band in verschiedenen gegeneinander in Bandlängsrichtung versetzten Lagen befestigbar ist.The invention solves the problem in that the excitation winding forms a separate from the carrier, enclosed by a sheath, the carrier consists of a closable around a body part tape and that the bobbin over the sheath on the tape in different mutually offset in the longitudinal direction of the tape Layers can be attached.
Die einen vom Träger gesonderten Spulenkörper bildende Erregerwicklung stellt eine wesentliche Voraussetzung für eine einfache Ausrichtung des durch diese Erregerwicklung erregten elektromagnetischen Feldes gegenüber dem zu behandelnden Körperteil dar, weil die Lage des Spulenkörpers gegenüber dem Körperteil optisch überprüft werden kann. Dazu kommt, daß der den Spulenkörper lösbar aufnehmende Träger aus einem um einen Körperteil schließbaren Band besteht, so daß der Spulenkörper mit Hilfe dieses Bandes lagegenau gegenüber dem zu behandelnden Körperteil festgelegt werden kann. Zu diesem Zweck ist lediglich für eine in Bandlängsrichtung versetzbare Befestigung des Spulenkörpers auf dem Band zu sorgen. Dies gelingt in einfacher Weise, wenn der Spulenkörper von einer Hülle umschlossen wird, die nicht nur den Spulenkörper schützt, sondern auch zur Verbindung des Spulenkörpers mit dem Band herangezogen werden kann.The excitation winding forming a coil body separate from the carrier is an essential prerequisite for simple alignment of the electromagnetic field excited by this excitation winding with respect to the body part to be treated, because the position of the coil body with respect to the body part can be checked optically. In addition, the support which detachably receives the bobbin consists of a band which can be closed around a body part, so that the bobbin can be fixed in position with respect to the body part to be treated with the aid of this band. For this purpose, it is only necessary to ensure that the bobbin is fastened to the tape in the longitudinal direction of the tape. This is achieved in a simple manner if the bobbin is enclosed by a sheath which not only protects the bobbin but can also be used to connect the bobbin to the tape.
Zur Befestigung der Hülle des Spulenkörpers in verschiedenen gegeneinander in Bandlängsrichtung versetzten Lagen kann das Band mit mehreren in Bandlängsrichtung versetzten Verschlüssen, beispielsweise Druckknöpfen, versehen werden, die mit einem entsprechenden Gegenstück auf der Hülle zusammenwirken. Besonders einfache Konstruktionsverhältnisse ergeben sich in diesem Zusammenhang, wenn die Hülle mit dem Band über einen Klettverschluß verbunden wird, der außerdem eine stufenlose Verstellung des Spulenkörpers auf dem Band erlaubt. Werden zwei oder mehrere Spulenkörper zur Erregung eines elektromagnetischen Wechselfeldes eingesetzt, so empfiehlt es sich, die Spulenkörper durch ein Kabel zu verbinden, das die Zusammenfassung der Spulenkörper zu einer Baugruppe sicherstellt, ohne die voneinander unabhängige Versetzung der Spulenkörper entlang des Bandes im Rahmen der Kabellänge zwischen den einzelnen Spulenkörpern zu behindern.To fasten the sleeve of the bobbin in different positions offset from one another in the longitudinal direction of the tape, the tape can be provided with a plurality of closures, such as push buttons, offset in the longitudinal direction of the tape, which interact with a corresponding counterpart on the sleeve. Particularly simple constructional relationships result in this connection if the sleeve is connected to the tape by means of a Velcro fastener, which also allows the bobbin to be continuously adjusted on the tape. If two or more bobbins are used to excite an alternating electromagnetic field, it is advisable to connect the bobbins by means of a cable, which ensures that the bobbins are combined to form an assembly, without the mutually independent displacement of the bobbins along the band within the framework of the cable length between to hinder the individual bobbins.

Weg zur Ausführung der ErfindungWay of carrying out the invention
Die dargestellt elektromedizinische Vorrichtung zur Erzeugung eines elektromagnetischen Wechselfeldes weist einen Träger 1 in Form eines Bandes 2 für zwei Erregerwicklungen auf, die vom Träger 1 gesonderte Spulenkörper 3 bilden. Diese Spulenkörper 3 sind von einer Hülle 4 umschlossen, die zur Aufnahme der Spulenkörper 3 eine durch einen Reißverschluß 5 verschließbare Öffnung aufweist. Über eine Steckkupplung 6 sind die miteinander über ein Kabel 7 elektrisch in Serie geschalteten Erregerwicklungen an ein Steuergerät angeschlossen, das die Erregerwicklungen mit einer elektrischen Wechselspannung einstellbarer Frequenz und Amplitude beaufschlagt.The illustrated electromedical device for generating an alternating electromagnetic field has a carrier 1 in the form of a strip 2 for two excitation windings, which form separate bobbins 3 from the carrier 1. These bobbins 3 are enclosed by a sheath 4, which has an opening which can be closed by a zipper 5 for receiving the bobbins 3. Via a plug-in coupling 6, the excitation windings, which are electrically connected in series via a cable 7, are connected to a control unit which applies an adjustable frequency and amplitude to the excitation windings with an electrical alternating voltage.
Die Hülle 4 für die Spulenkörper 3 der Erregerwicklungen sind mit Klettverschlußstreifen 8 versehen, mit deren Hilfe die Spulenkörper 3 über die Hüllen 4 am Band 2 befestigt werden können, das als Gegenstück mit den Klettbändern 8 einen Klettverschluß ermöglicht, der ein Versetzten der Spulenkörper 3 entlang des Bandes 2 erlaubt. Das Band 2 selbst weist einen lang des Bandes 2 erlaubt. Das Band 2 selbst weist einen ebenfalls mit einem Klettband versehenen Endabschnitt 9 auf, der beim Umschließen eines Körperteiles 10, beispielsweise eines Armes, eines Beines oder eines Rumpfes, den gegenüberliegenden Endabschnitt des Bandes 2 übergreift und mit diesem einen Klettverschluß bildet, so daß das den Träger 1 für die Spulenkörper 3 bildende Band 2 mit einer für die Halterung der Spulenkörper 3 auf dem Körperteil 10 ausreichenden Zugspannung den Körperteil 10 umschließen kann.The sleeve 4 for the coil former 3 of the excitation windings is provided with Velcro strips 8, by means of which the coil former 3 can be fastened to the belt 2 via the sleeves 4, which, as a counterpart with the Velcro strips 8, enables a Velcro fastener which moves the coil former 3 along of volume 2 allowed. The tape 2 itself has one allowed along the length of volume 2. The band 2 itself has an end section 9 which is also provided with a Velcro strip and which, when enclosing a body part 10, for example an arm, a leg or a torso, engages over the opposite end section of the band 2 and forms a Velcro fastener with it, so that this forms the Carrier 1 for the bobbin 3 forming band 2 can enclose the body part 10 with sufficient tension to hold the bobbin 3 on the body part 10.
Da die Spulenkörper 3 über die Hüllen 4 je für sich in Längsrichtung des Bandes 2 versetzt werden können, ist eine optisch überprüfbare Ausrichtung der Erregerwicklungen für das elektromagnetische Wechselfeld gegenüber dem zu behandelnden Körperteil 10 ohne weiteres möglich. Damit kann im Bereich des zu behandelnden Körperteiles eine ausreichende Feldstärke sichergestellt werden, und zwar ohne übermäßigen Energieeinsatz. Außerdem kann durch die gezielte Ausrichtung der Erregerwicklungen gegenüber dem zu behandelnden Körperteil 10 das elektromagnetische Wechselfeld im wesentlichen auf den zu behandelnden Körperteil beschränkt werden.Since the bobbins 3 can each be displaced in the longitudinal direction of the strip 2 via the sleeves 4, an optically verifiable alignment of the excitation windings for the alternating electromagnetic field with respect to the body part 10 to be treated is readily possible. Adequate field strength can thus be ensured in the area of the body part to be treated, without excessive use of energy. In addition, through the targeted alignment of the excitation windings with respect to the body part 10 to be treated, the alternating electromagnetic field can essentially be limited to the body part to be treated.
Die Erfindung ist selbstverständlich nicht auf das dargestellte Ausführungsbeispiel beschränkt. So kann die Versetzung der Spulenkörper 3 in Längsrichtung des Bandes 2 auch mit anderen Verschlüssen als Klettverschlüssen erreicht werden. Es kommt ja lediglich auf die Versetzbarkeit, nicht aber auf die Art der versetzbaren Befestigung an. Gleiches gilt für die Verbindung der Endabschnitte des Bandes 2, das zu einer Schlinge unterschiedlicher Länge zu verbinden ist. The invention is of course not limited to the illustrated embodiment. Thus, the displacement of the bobbin 3 in the longitudinal direction of the tape 2 can also be achieved with closures other than Velcro closures. It only depends on the displaceability, but not on the type of the displaceable fastening. The same applies to the connection of the end sections of the band 2, which is to be connected to form a loop of different lengths.
